The UN on Thursday said fighting between eastern Libyan forces and Tripoli government troops had killed 56 people and forced 6,000 to flee their homes in the capital in the last week.
This has made France and Italy to wrangle over how to respond to the renewed conflict.
After sweeping up from the south, the Libyan National Army (LNA) forces of Khalifa Haftar have been blocked in the southern suburbs of Tripoli about 11 km (7 miles) from the centre.
Haftar’s push for Tripoli is the latest in a cycle of violence and chaos in Libya since the 2011 overthrow of former strongman Muammar Gaddafi.
In Rome, Libya’s former colonial ruler Italy warned France, which has close ties to Haftar, to refrain from supporting any faction after diplomats said Paris blocked a EU statement calling on him to halt his offensive.
“It would be very serious if France for economic or commercial reasons had blocked an EU initiative to bring peace to Libya and would support a party that is combatting,” Deputy Prime Minister Matteo Salvini said.
“As minister of the interior I will not stand by and watch.”
France, which has oil assets in eastern Libya, has provided military assistance in past years to Haftar in his eastern stronghold, Libyan and French officials say.
It was also a leading player in the war to unseat Gaddafi. Italy supports the UN-backed government of Serraj.
“Some think that the (2011 Nato-led military intervention) in Libya promoted by (former French President Nicolas) Sarkozy was triggered more by economic and commercial interests than by humanitarian concerns,” he said.
“I hope we are not seeing the same film all over again.”
An EU draft statement on Wednesday said Haftar’s attack on Tripoli put civilians at risk, disrupted the political process, and risked an escalation with serious consequences for Libya and the wider region.
French diplomatic sources said on Thursday Paris did not object to calls on Haftar to stop his advance, but had only requested amendments including mentions of migrants’ plight and the presence among anti-Haftar fighters of militants designated as terrorists by the UN.
The latest tally of casualties from the UN WHO said 56 people – mainly fighters though also some civilians including two doctors and an ambulance driver – had been killed, and another 266 wounded in Tripoli.
The number of people forced out of their homes doubled in the last 48 hours to 6,000, UN humanitarian agency OCHA said.
As well as the humanitarian consequences, renewed conflict in Libya threatens to disrupt oil supplies, increase migration across the Mediterranean to Europe, scupper the UN peace plan, and encourage militants to exploit the chaos.
Libya is a main transit point for migrants who have poured into Europe in recent years, organised by illegal trafficking gangs.
The LNA forces moved out of their stronghold in eastern Libya to take the sparsely-populated but oil-rich south earlier this year, before heading a week ago toward Tripoli, where the internationally-recognised government of Serraj sits. (Reuters/NAN)
